1. First you need to connect your iPhone or iPad to Mac or PC. By default, when you plug in your iOS device, iTunes opens automatically. Make sure you close iTunes before you proceed further.

2. Now open Cydia Impactor app and drag-and-drop the downloaded Kodi .IPA file you downloaded earlier from the link we shared above.

3. Select your iOS device in the drop-down menu and click on "Start."

4. Now, you'll see Cydia Impactor app asking for a valid Apple ID to proceed further. There is no harm in entering your Apple ID here, it is only used for IPA file. You can alternatively use a pseudo ID if you don't want to share your personal details.

5. When the app is installed, go to Settings - General - Profiles & Device Management. Now find your Apple ID profile and open it.

6. Tap on the "Trust" button so your iOS can trust the newly downloaded Kodi app.
